Concentrated nutritional or supplemental compound for intestinal, gut-brain axis and neurobiological homeostasis through calibrated absorption including neurotransmitter or any equilibrating compound release to treat or mitigate disease and co-morbidities, particularly obesity and malnourishment

ABSTRACT

The gut-brain axis, neurobiology and neurotransmission are physiologic systems with known pathways, yet they are rarely leveraged for wellness, notwithstanding extensive literature regarding healthy diets and nutrition. Gastrointestinal (GI) evolution has equipped humans with exceptional plasticity for food abundance or scarcity, while maintaining homeostasis by producing essential neurotransmitters that drive fundamental behaviors, from seeking nourishment to engaging in routine tasks of life. The advent of cheap, abundant, and highly processed foods in the last century, however, has upended the very systems that evolved for survival with a debilitating propensity for obesity in abundance—and malnourishment where access may be limited to a scarce supply of such processed foods, or none at all. In short, a better understanding and application of physiologic signaling and equilibrium is needed in cases of weight management and malnourishment. Neurotransmitters, especially serotonin, are the primary moieties that have beneficial capacity in routine tasks, consuming but not overconsumption of needed sustenance, and achieving wellness overall. Thus, this invention provides a novel delivery mechanism of micro-dosed, natural ingredients for stimulating production of a calibrated serotonin level by leveraging the gut-brain axis through organic nutrient conversion without synthetic pharmacologic compounds. Herein, specifically engineered foodstuff that converts to serotonin (or other mediators of neurobiology) is designed to facilitate weight management and may be applied to mitigate risks of malnourishment maladies such as childhood stunting by employing directed neurobiology.

FIELD OF THE INVENTION

The present invention is in the field of wellness achieved through neurotransmitter stimulation for weight management, the prevention and treatment of obesity, related comorbidities, and general and childhood systemic privation.

BACKGROUND OF THE INVENTION

Epidemiologists consider the obesity epidemic a public health crisis which is exacerbated by the ubiquity of energy-dense, hyperpalatable food that drives overindulgence and overwhelms evolutionary homeostasis [Blither, 2019]. Obesity is diagnosed when an individual's body mass index (BMI) exceeds 30 (kg/m²), with BMI of 25 or greater categorized as overweight [Pi-Sunyer, 2000]. In 2020, more than 2 billion adults (39% of the global population) were clinically considered overweight; of these, 600 million were classified as obese [WHO, 2020]. The condition results in excess body fat accumulation that negatively affects most metabolic systems with associated risks and predisposition to an array of diseases (comorbidities). Globally, the economic impact of obesity from related health care, reduced life expectancy, disability and lost productivity costs has been estimated at nearly $1.4 trillion (USD) [Lopez et al., 2020].

While dietary and some surgical interventions represent the cornerstones of obesity treatment, most approaches have fallen short and remain widely debated among health professionals and the general public. Adolescent obesity is particularly associated with psychological disorders including depression, anxiety, and despair, which often leads to invasive bariatric procedures [Lindberg et al., 2020] for those with the means and access to such interventions. Given that weight loss is typically a gradual process, a key limitation to successful dietary intervention is the relentless risk of diminished patient resolve. Effective weight loss dietary strategies can thus require biological and psychological habituation. Yet, most solutions have remained elusive due to cost and/or limited access to invasive procedures; whereas, dietary approaches routinely challenge patient determination. These factors are increasingly common among lower-income communities and most prevalent in emerging countries.

Biochemically, minor imbalances (e.g. impact of irregular sleep patterns on leptin and ghrelin, hormones that drive perceived appetite) can drive significant metabolic changes and lead to excessive weight gain. Morbid obesity is a recent phenomenon circumspect to post-World War II industrialization and a surfeit of readily accessible, often processed, and not always nutritious, foodstuffs that can overwhelm circadian neurotransmitter systems that evolved under conditions of intermittent access to nourishment [Cutler et al., 2003; Galyean, 2012]. As circadian biochemistry remains relatively unchanged, the capacity to compensate for overeating has not similarly evolved. However, gastrointestinal (GI) neurobiology has established circadian rhythms that are typically manifested in the synthesis of proteins and peptides that automatically regulate physiologic systems throughout the body—and throughout the day. Notably, neurotransmission of serotonin and oxytocin occurs throughout the body and particularly the GI tract, sending critical metabolic signals to the brain and in turn, stimulates conscious perceptions including fullness or hunger, energy or fatigue, and related conditions.

The human body requires relatively minimal nutritional extraction given nutrient variety, complexity, and volume of indigestible matter. If variety and/or complexity are lacking, however, additional mass is required. The gastrointestinal tract thus accommodates such variables spanning nutrient assortment, food scarcity and abundance, and cognitive caloric fuel requirements. Thus, the digestive system had notably adapted to foodstuff privation and abundance with only rare instances of obesity prior to recent sociological and dietary shifts in work patterns and processed food abundance and access.

When such foods are readily available in societies where specific meals are traditionally consumed, continuously eating can occur in response to stomach emptying. The stomach serves as a highly acidic, transitional organ that aids absorption by optimizing digestion before emptying. During a fast, however, ingested material is quickly transferred to the small intestines. This transfer results in a short-lived, rapid spike in the neurochemical milieu created by the small intestines and communicated to the brain. Such spikes and falls can result in a cycle of overeating relative to basal caloric requirements. Similar responses occur at usual meals; whereby the combination can lead to weight gain and ultimately, obesity.

Given that neurotransmitter processing and stimulation are accomplished in the small intestines and thus, minimal stomach involvement is required, wellbeing and weight management may be achieved via routinely longer fasting periods with as little as a single daily meal. This is also known as “intermittent fasting.” Beyond volume, a truncated eating period requires nutritional variety to fuel intricate biological functions, as well as satisfy the psychological complexities associated with taste and texture. However, adherence to such regimens is challenging and often stressful. In this patent, novel innovation that bridges gut-brain axial signaling is aimed to facilitate dietary interventions for weight management via imperceptible neuropeptide signaling.

Prefrontal cortex activity is diminished during fasting, which regulates brain functions such as logic, reasoning and planning, as evidenced by fMRI analysis [Van Galen et al., 2018]. This region also helps curb impulses associated with appetite and food cravings. During a fast, these activities shift from the prefrontal cortex to the limbic system (i.e., hypothalamus, thalamus, and nucleus accumbens) which can stimulate perceptions of hunger. The transition from prefrontal to limbic activity is associated with behavioral responses to the biological requirement for sustenance and perceptions of food scarcity conditions.

Specifically, the neural framework associated with the gut and the brain that regulates eating behaviors can be manipulated to control appetite. The brain, particularly the limbic region (i.e., hypothalamus) plays a crucial role in modulating food intake by sensing molecules and metabolic signals. Post-ingestion, intestinal absorptive sites stimulate neural pathways that mediate the transmission of nutritional signals from the gut to the brain and elicit perceived wellbeing or equilibrium. Principally, food intake is controlled via two brain mechanisms or circuits [Lutter and Nestler, 2009]: The homeostatic circuit matches energy intake and output, and a “hedonistic” pathway that drives reward mechanisms, both of which are linked to serotonin [Van Galen et al., 2021].

Serotonin is a monoamine neurotransmitter that also acts as a hormone and carries essential messages between nerve cells in the brain and throughout the body. The fundamental role of serotonin in food intake, mood, and other circadian patterns (e.g., sleeping) has been well researched and characterized [Wurtman, 1993; Dugovic, 2001; Strasser et al., 2016]. As brain serotonin production is modest, up to 90% of endogenous serotonin production that occurs in the GI tract is required. By enabling synaptic communication between the brain and the gut, serotonin plays a critical role in numerous circadian functions. However, maintaining serotonin levels is delicate, and imbalances can be deleterious, often associated with selective serotonin reuptake inhibitors (SSRI) and serotonin blocking therapeutics [Koyuncu et al., 2012].

Designing a serotonin regulating supplement to curb brain impulses arising from neurochemical imbalances could achieve homeostatic levels of serotonin, resulting in a relative state of psychological equilibrium. Steady-state, trace serotonin production that emanates through the gut-brain axis could thus achieve homeostasis. Due to characteristic rapid stomach emptying, a supplement can be engineered to pass through the stomach and duodenum intact. As such, foodstuff designed for absorption exclusively in the small intestines holds functional advantages with respect to weight loss. The process would enable prolonged, calibrated delivery to result in greater digestive energy expenditure than caloric absorption; and conversely, more easily digested energy requirements for faster assimilation.

As such, neuro- and circadian biology can be leveraged to effect weight loss and establish a healthy BMI. While it might appear antithetical to use nutritional intake to achieve a healthy BMI, this invention drives a circadian cycle of serotonin stimulation to achieve caloric homeostasis to facilitate adherence during weight loss while mitigating anxiety. Accelerated absorption can also be calibrated for treatment of malnourishment.

For weight management, a compressed, calorie-dense tablet or capsule would thus increase compliance and afford convenience. By requiring more calories for absorption than caloric content, the net effect is to shift digestion dynamics, such as intestinal peristalsis, surface or contact area exposure and enzyme production and utility. This invention takes advantage of the gut-brain axis, neural connections between the enteric nervous system of the small intestines and the central nervous system, nutrient digestibility, neurotransmitter stimulation, gastric emptying and transit times. It also provides a novel delivery form that produces steady serotonin flows to the brain using natural foodstuffs, compression, and/or coatings and administration to bypass initial stomach digestion for absorption entirely inside the small intestines. Ingestion of one or more doses during a fasted state would provide a method for sustained serotonin signaling and psychological equilibrium.

The use of low energy dense foods that impart significant volume to the stomach and GI tract resulting in overall reduced caloric intake have been previously described. For example, U.S. Pat. No. 5,336,486 describes a vegetable fiber that induces satiety via filling the stomach. In addition to compliance issues, these methods are associated with GI discomfort and flatulence produced by gut microbiota. To counteract volume expansion issues, the use of easily digestible products with minimal caloric density have also been described in U.S. Pat. Nos. 5,063,073; 5,654,028 and 6,426,077. Additionally, the use of collagen-based biopolymers and gelatin formed into hydrophilic powders, granules or pellets with poor absorption kinetics have been previously explained in U.S. Pat. No. 6,103,269. The use of porcine gelatin capsules that contain absorbent hydrogel particles designed to form a three-dimensional bulk matrix in the stomach was described in U.S. patent application Ser. No. 15/942,655. The prior art associated with these inventions has thus relied primarily on physical mass and low-calorie, poorly digestible compositions that simulate sensations of satiety, hence give rise to poor compliance in the absence of actual nutrients. The object of the present invention is not associated with vegetable fibers, biopolymers or hydrogels that induce satiety by filling stomach volume.

U.S. Pat. No. 8,562,952 describes a method of inducing satiety via a serotonin receptor agonist, serotonin re-uptake inhibitor, or serotonin. The patent describes suitable compositions of peptide YY (and functional analogs), calcitonin gene-related peptide, an adrenergic agonist, an opioid agonist, or combinations thereof. Addition of an active lipid may be used to prolong GI dwell time to enhance dissolution, bioavailability and absorption. The proposed invention differs from the previous art in composition, does not include peptide YY, calcitonin gene-related peptide, an adrenergic agonist, an opioid agonist, nor is the use of an active lipid required.

Derived from natural ingredients, such as those in chicken eggs and cow's and/or goat's milk—or plant-based proteins in alternative embodiments, the composition of the present invention is a novel delivery mechanism for organic nutrients, and not synthetic molecules. The mode of action associated with the present invention deviates from the current art associated with system suppression, restriction, indigestible bulk, and physical manipulation for weight management.

This invention employs strategic engineering of micro-dosed nutrients that alter the delivery pathway to influence brain function without caloric density. The invention further provides a method and composition that quickly evacuates the stomach, feeds the small intestines and by extension, the brain, via the gut-brain axis. This affords a calibrated stimulation of serotonin from micro-absorption of essential nutrients using intense intestinal peristalsis and energy, resulting in a net negative calorie ingestion and neural and psychological stasis.

BRIEF SUMMARY OF THE INVENTION

The present invention provides a novel solution for the treatment of obesity, weight management (and related comorbidities), childhood systemic privation and general wellness using an enteric, solid form administration (e.g., tablet, capsule, pellet, granule, etc.). The present invention is comprised of micro-dosed, low-volume and nutrient dense egg and milk formulated to bypass stomach digestion processes. The composition of the present invention modulates serotonin production in the brain and is useful for appetite management and treating nutrient deficiencies such as those associated with stunting. In some instances, the present invention may be useful for surgical preparation and post-operative recovery or during potentially debilitating treatment routines.

Compacted into a dense, solid tablet, the invention can be ingested without chewing. When taken at least 2 hours after eating, the enteric coating would be dissolved only upon transfer to the small intestines (pH and peristalsis driven), without stomach processing, nutrient modification or loss from inertial forces that grind and mix disintegrated contents prior to passing through the pyloric sphincter. Notably, while empty, stomach muscle contractions are minimal until a myoelectric complex rapidly stimulates evacuation of its contents. Thus, with rapid delivery of the invention to the small intestines, the GI contraction, torque and crushing forces would then allow for calibrated absorption. Given optimal transit time of ingested material and associated energy (caloric) consumption from peristalsis, an extended, continuous stimulation of serotonin production would thus promote psychological equilibrium.

However, meal timing and nutritive density of consumed foods can impact stomach emptying, which is necessary for this invention to promptly transfer to the small intestines. In turn, while leaning towards the right side can accelerate transfer to the small intestines [Lee et al., 2022], it would not be sufficient to ensure the intended use of this invention. As most absorption takes place in the small intestines, gastric emptying times would thus represent a rate-limiting step in delivery. The gut-brain pathway is calorie independent, and while the composition of the present invention is nutritive, more calories would be expended than consumed. That is, the delivery of intact, compressed nutrient tablets to the small intestines, without significant stomach breakdown, would thus require digestive processes that require more metabolic energy than contained in the tablets.

The present invention further embodies a preparation of proteins and micronutrients found in eggs and milk with distinct biologic properties. Eggs obviously facilitate reproduction and provide nutrition from conception to hatching, and milk is easily digestible (with lactose neutralization for many adults), while providing cognitive and immune support. When lyophilized, the stability and therefore, shelf life, of these materials are superior to most supplements and foodstuffs, which can also provide commercial and storage advantages that help ensure the integrity of these ingredients.

Beyond weight management, the composition of the present invention has potential malnourishment applications. The benefits could ease food security challenges, which have been exacerbated by climate change impact on agriculture and viable grazing access. Traditionally, wheat, maize and flour are commonly distributed to fight hunger. While grain has been historically considered a food staple with various essential vitamins, these carbohydrates are nonetheless lacking in other critical nutrients. The invention could thus provide a supplement to such practices with complementary sustenance.

DETAILED DESCRIPTION OF THE INVENTION

The materials, compounds and composition described below are to be considered exemplary and explanatory, but not limiting. The present invention relates to tablets prepared from a blend of eggs and milk, and optionally additional binders, excipients, or fillers that are engineered for release in the small intestines to stimulate serotonergic signaling. The materials are stepwise metabolized by the gut microbiota into indole and indole derivatives and subsequent synthesis by enterochromaffin cells to produce serotonin. In alternative embodiments, it would be obvious to include additional beneficial ingredients or other advantaged chemistry to the composition, such as folic acid, formulated to support planned pregnancy.

The active ingredients of the primary embodiment of this invention comprise lyophilized chicken eggs and cow's and/or goat's milk. The material form of these active ingredients demonstrates compatible tableting substances with robust shelf stability. The constituents are accessible and affordable, representing ideal raw materials for diverse applications and populations. The invention utility is focused on human weight and nutritional management; however, embodiments could be adapted for domesticated or wild species.

The essential macronutrients in eggs support numerous biological functions, including nutritive molecules that act as precursors, required for cell division, growth, membrane signaling and brain function [Caudill, 2010; Zeisel & Niculescu, 2006]. The protein profile of the egg matches human dietary requirements and contains all non-essential and essential amino acids. In addition to protein, the fatty acids of egg yolks (in particular, DHA) are likewise vital for cognitive, neurologic, and optical sustenance.

Milk is a mammalian-derived emulsion of oil in water that contains bioactive proteins, lipids and saccharides, as well as antibodies, enzymes, antimicrobial peptides, oligosaccharides and hormones [Pouliot and Gauthier, 2006]. Thus, milk provides energy, essential amino acids, fatty acids, vitamins, and diverse inorganic elements. Like eggs, milk proteins include all essential and non-essential amino acids, as well as caseins and whey protein with rich nutrient value and high digestibility for efficient absorption and utilization. Uniquely, lactose [β-d-galactopyranosyl-(1→4)-d-glucose] is a carbohydrate and the most abundant component by weight in lyophilized milk. Lactose has low hygroscopicity, physical and chemical stability, and water solubility properties that have led to wide utilization as an excipient binder in tablets. The inclusion of lactose during compounding optimizes viscosity, compaction, and bulking density properties. Depending on the tablet manufacturing method and release characteristics, inclusion rates of lactose vary from 30% to over 50%, which can offset other active ingredients. As lactose is a key constituent of lyophilized milk, dosing strategies can be controlled without supplemental excipient requirements, thus conferring additional benefits to tablet formation of the present invention. The composition of lyophilized milk creates an excellent nutritional source for infants that is digestible, well tolerated, and optimized for efficient nutrient uptake during the first year of life. As such, it may also be readily optimized for GI maturation stages from neonates, to infants, children, adolescents, adults, seniors and the infirm of any age.

In an alternative embodiment, a vegan substitute with a suitable amino acid profile may be preferable. Such substitutions may include chia seed protein, hemp protein, pea protein, pumpkin protein, rice protein, soy protein, sunflower protein, or other plant-based source containing tryptophan. In yet another alternative embodiment, the user may have an intolerance to egg and/or milk products. In the case of milk (lactose) allergies, the tablet can be formulated to contain lactase enzymes to aid digestion. While egg allergies are often outgrown in the first five years of life, some infants and adults may have adverse reactions to the egg albumin, yolk or both. Thus, a modified dosage comprising a higher concentration of lyophilized milk or a combination of lyophilized milk and another suitable plant-based protein may be preferred.

Food is not only necessary as metabolic fuel for the body but has a profound role on brain function, which is not typically considered when evaluating diet for weight management. Tryptophan is essential for human life but is not biologically synthesized. The majority (>90%) of ingested tryptophan is converted into biomolecules for neurological signaling [Strasser et al., 2016]. The amino acids in eggs and milk include significant levels of L-tryptophan compared to other foods [Singh, 2019]. Tryptophan is a precursor for serotonin, a known peripheral satiety signal that acts through the afferent vagal nerve pathway [Schaechter and Wurtman, 1990].

The serotonergic system of the brain and GI tract play synergistic roles in the control of food intake and whole-body energy homeostasis. Over-stimulation of serotonin production can cause negative side effects as reported with administration of some pharmaceuticals that alter biologic levels. Increased administration of serotonin precursors (i.e., tryptophan rich foods) has also proven ineffective, because serotonin must compete with other large neutral amino acids (LNAA) to cross the blood-brain barrier [Stone and Darlington, 2013]. Typical of foodstuffs with diverse amino acid profiles, the net effect of tryptophan is notably lost when excess LNAAs are also present. The micro-dosed, solid composition of the present invention combines balanced tryptophan concentrations with extended release of serotonin production stimulants directly to the absorptive sites of the small intestines.

The process of satiation, or perceived indifference to eating, can be mediated by serotonin-containing neurons and pathways, as evidenced by pharmacological manipulation with serotonergic drugs [Blundell, 1984]. Studies of receptor blocking, systemic administration (of serotonin) [Fletcher and Burton, 1986], use of selective serotonin reuptake inhibitors (SSRI) [Gafoor et al., 2018] and molecular neuroimaging [Van Galen et al., 2018] have characterized the role of serotonin signaling in eating behavior and long-term weight regulation. In the primary embodiment of the present invention, a solid composition, or tablet, would be administered and engineered to rapidly evacuate the stomach. It would then stimulate calibrated, trace serotonin production in the small intestines into the bloodstream to induce psychological equilibrium, which can facilitate extended fasting between meals.

In the present invention conforms to circadian rhythms that require homeostasis relative to periods of rest and activity. This aspect is imperative due to the complex neural network of the GI tract that influences cognition, mood, stress, decision making, and perceived well-being. System stability or homeostasis can be achieved through the formulation, dosage, timing and delivery mechanisms described in this patent. The relative concentrations of serotonin-stimulating amino acids of the present invention are calibrated and formulated to avoid competitive inhibition, excessive hormone stimulation and negative biologic disparities.

In the primary embodiment of the present invention, the tablet composition is directed towards achieving equilibrium with respect to brain stimuli that govern homeostasis and cognition. The composition is manufactured free of disintegrants typically employed in tableting processes. As such, disintegrants are used to facilitate rapid breakdown and provide immediate release or delivery of active ingredients. Whereas inclusion of disintegrants would impact serotonergic signaling from a synaptic response immediately after ingestion. The preferred use of this invention is directed to stimulate continuous, low-level serotonin signaling between the gut-brain axis.

Alternatively, in another embodiment, the tablet would deliver dense nutrients to treat deficiencies and maladies caused by chronic conditions of hunger (e.g., stunting) and as a healthcare supplement during debilitating or potentially toxic treatment (e.g. radiation and chemotherapy). As it is essential to ensure an individual's robustness to endure any intervention, administration could be applicable prior to such procedures or as a presurgical supplement to boost vigor and aid recovery. The composition of such an embodiment would be similar, however, dosing regimens, concentrations, frequency, and timing would vary depending on individual or therapeutic requirements. In such alternative embodiments for use beyond weight management, the inclusion of a disintegrant may be beneficial to facilitate faster absorption and nutrient uptake.

Traditional tablet manufacturing requires the use of filler agents or excipients that create intergranular bonds and fuse the materials together to impart tensile strength. Common binders include cellulose derivatives, gelatin, polyvinylpyrrolidone, starch, sucrose, and zinc stearate. The active ingredients of the invention contain lactose, which is also an established binding additive and would obviate the need for additional binding agents. However, a compression lubricant to prevent tablet cracking and allow for smooth ejection after compression may be used to prevent the lyophilized material from sticking to the compression die or punch. Common lubricants include calcium stearate, magnesium silicate, magnesium stearate and stearic acid. In the preferred embodiment, magnesium stearate, a metallic salt boundary lubricant, is used for tablet formation due the material cost, lubrication capabilities, high melting point and chemical stability.

In the preferred embodiment of the present invention the tablet can be formed in different sizes. According to Food and Drug Administration (FDA) recommendations for swallowing, the overall size of the tablet should be no larger than 22 mm. The typical tablet range for the preferred embodiment is 1 to 22 mm, depending on the concentration of the ingredients. Given the lack of binders, fillers or excipients required for tableting, dosing is not compromised by size. Should smaller tablets be desired, ingredient concentration and frequency may be varied accordingly. In alternative embodiments, it would be obvious that the tableted lyophilized material described could be encapsulated in an alternative container designed for oral administration.

In the present invention, the tablet may be compressed or molded in a variety of shapes, sizes and weights, and the delivery form is preferably solid. Common tablet geometries include round, oval, oblong, square, rectangular, diamond, triangular, pentagonal and a core rod. In the preferred embodiment of the invention, the tablet is oblong, which can facilitate swallowing by optimizing length, width and thickness. In alternative embodiments, the tablet may be formed in layers or segments that disintegrate at different rates. The calibrated dose of the preferred invention is thus based on tablet size, geometry, and specific use, whereby frequency and quantity can be varied.

In a preferred embodiment, the invention is intended for oral administration on an empty stomach. While oral consumption is preferable in terms of compliance and cost, the delivery method faces several challenges during transit through the GI tract. In the primary embodiment of the present invention, tablets are enterically coated to protect against digestive acids in the gastric juices of the stomach and ensure intact transfer to the small intestines. The enteric coating on the tablet may comprise of polymers and copolymers such as butyl stearate, carnauba wax casein, cellulose acetate, ceresin, dextrin phthalates, ethyl acrylate, hydroxypropyl methylcellulose, keratin, methacrylic acid, methyl methacrylate, methyl phthalyl cellulose, paraffin, shellac, or another copolymer of anionic character. The enteric coating polymer can be the same or different from any polymer in the protective coating and can be one or a combination of polymers and/or copolymers. The enteric coating that protects the tablet from stomach acids can vary between tablet layers, and individuals with stomach-emptying abnormalities (e.g., complications of duodenal ulcers) may require additional coating strategies to benefit from this invention.

Amino acid absorption in the small intestines does not require pre-digesting in the stomach. In the present invention, timing of tablet administration and engineering are essential to facilitate rapid stomach evacuation through the upper anastomosis and into the small intestines, thereby allowing for adequate time and exposure to the small intestines to optimize nutrient absorption. Notably, the membranes in the small intestines are far more permeable than those in the stomach.

The rate at which matter passes through the stomach and GI tract determine the ultimate absorption of the ingested material. Delivering these compounds through a tablet metabolized in the small intestines provides greater nutrient uptake and utilization. In the present invention, physiological balance and psychological equilibrium from continuous trace serotonin stimulation avoid the spikes and drops typically caused by randomly eating throughout the day, likewise imparting mood neutrality, and a perception of wellness. This invention thus facilitates optimal food intake when subliminal stimulation of serotonin levels and gut-brain neurotransmitters are calibrated to achieve homeostasis.

In a preferred embodiment, the coated tablet bypasses stomach pre-digestion followed by measured GI disintegration to allow for sustained, gradual absorption and signaling between the gut-brain axis. The protective coating is degraded upon transfer to the small intestines, thus delivering the compacted active ingredients. In the intestines, mechanical forces and torques applied by peristaltic contractions aid disintegration and disaggregation and allow for dissolution of the lyophilized egg and milk. Disintegration is stepwise due to compaction of the material; thus, granules are first produced and more slowly disaggregated, resulting in fine particle formation. A single tablet can reside in the small intestine for as long as four hours or more, as surface area is slowly increased by the muscular activity of the intestines.

The FDA defines tableting and capsule coatings and formulations with respect to immediate release, extended-release, delayed-release, or sustained-release, which are accomplished by the compound or compounding of the material. Typically, this is accomplished through the application of a coating material with pH resistance, and/or addition of a commercially available hydrophilic matrix or suitable binder material. Given that gastric emptying times, pH levels and numerous oral/GI biological factors are highly variable from patient to patient, oral administration based on compounding can be disadvantaged. The proposed invention is nonetheless intended for administration after stomach emptying and engineered to allow continuous peptide release and neurobiological stimulation in the small intestines when applied to weight management. Exposing orally administered matter to stomach acids for unpredictable periods can diminish efficacy, uptake, bio-assimilation, predictability, delivered dosage, and can also alter or change the structure and compatibility of the material. Current enteric coatings may delay the decomposition of a delivered agent by resisting harsh stomach acids, but absent compacting as applied in this invention, these coatings would not control release rates upon intestinal transfer to the same degree.

A primary aspect of the present invention is tablet design to ensure appropriate, sustained delivery in the small intestines for optimal digestion and controlled biochemical stimulation. In one embodiment of the present invention, the tablet is formed by compacting a powder blend in a die and punch tooling system. The compression force of the tooling system is between 10 (99.6 kN) to 100 (996.4 kN) tons. Tablet compacting can be performed under vacuum with or without in-line cooling. In the primary embodiment of the invention, the powder blend includes defined percentages (by weight) and ratios of lyophilized egg and milk protein, wherein the lactose composition of the lyophilized milk serves as the meltable binder. Optionally, another suitable binder may be added to the powder mix to increase matrix bindings. In some embodiments, a suitable lubricant may be added to the powder to aid in tablet formation and ejection during manufacturing. In the preferred embodiment of the invention, no engravings or special features that would alter compaction are etched onto the tablet.

In an alternative embodiment of the present invention, lyophilized eggs and milk would be encapsulated in alginate microspheres—in lieu of compression, to calibrate absorption. The pKa of the alginate microspheres are stabilized by intermolecular hydrogen bonds that are easily broken in the intestinal fluid but remain stable in gastric fluids. The microencapsulated, lyophilized egg and milk alginate complexes are formed via freeze drying. Spray dried, lyophilized egg and milk powder form a uniform, fine particulate powder of approximately 5 microns. The calcium containing spray-dried material is subjected to reverse spherification to create a hard outer shell formed by the cross-linking reaction of alginic acid and calcium. Spray drying is a cost-effective, scalable technique to create uniform encapsulated material.

In a similar embodiment, the lyophilized egg and milk material are combined with alginate and vigorously mixed. The solution is forced through an orifice under high pressure and passed through an atomizer to create cross-linked microspheres that have a dense calcium-alginic acid outer shell containing a liquid core comprised of the constituent parts of the lyophilized eggs and milk that remain uniform while encapsulated by, but not incorporated into, the crust of the sphere. After microspherification, the material can be dehydrated or subjected to freeze drying. In some embodiments, the freeze-dried microspheres are subjected to a second alginate coating, which may comprise a defined concentration of individual microspheres created in the previous step. The resultant material may be exposed to a second freeze-drying procedure and then subjected to traditional tableting and enteric coating processes. The concentration of alginate can be varied to tailor shape, viscosity, aspect ratio and the interfacial tension of the formed microspheres.

In various embodiments of the preferred invention, the inclusion of phenazopyridine hydrochloride may be added to the composition for digestion analysis and quality control. This over-the-counter active ingredient is a poorly soluble dye routinely used to alleviate the symptoms of urinary tract infections and impart a reddish-orange color to the urine. During manufacturing, phenazopyridine can be added to specific layers, incorporated into the core, mantle or surface of the tablet. The dye can be easily visualized by examining urine color change as early as 20 minutes, but within one hour after ingestion [Hui et al., 2009]. Analysis of urine characteristics in this embodiment may thus be used to confirm initial tablet disintegration and dissolution in the small intestines.

In the present invention, the tablet is intended for administration on an empty stomach to facilitate rapid transfer to the small intestines caused by fasted state metabolic spikes that enable gastric emptying. The tablet contains multiple layers of protection that both stabilize the lyophilized material and prevent breakdown in low pH environments. After transfer to the small intestines, the enteric coating is degraded, and the compressed spray dried alginate microspheres and dual layer alginate microspheres are slowly disaggregated by peristaltic contractions. Individual microspheres are then disintegrated to release encapsulated materials, either small spheroid substances (dual encapsulated) or lyophilized milk and egg constituent parts and amino acids into the small intestines for uptake. The dwell time of the material can be customized depending on the percentage of alginate, the degree of spherification, the formed layers, dual encapsulation methods and particle size to tune release kinetics of the material.

Extended duration pharmacological methods are typically based on administration pathways and not specifically engineered for controlled intestinal uptake over time. Time-release encapsulations are commonly engineered coatings of bolus dosages that avoid stomach acids to facilitate delivery to the small intestines—and in some cases, to maintain molecular integrity otherwise lost in gastric fluids. Similarly, liposome encapsulation is typically applied to delayed bolus administration as opposed to uptake dependent on peristalsis and digestion. This invention calibrates dosages over time by slowing the dissolution for prolonged absorption. The invention would therefore be obvious and suitable for delivery of therapeutics where micro-dosing and calibrated release or sustained dosing would be beneficial (e.g., iron supplementation, other neurotransmitters, pharmaceuticals, vitamins, supplements, foodstuff, or nutraceuticals, including micronized sustenance for privation and malnutrition).
